| Synopsis | Hermes summons Wonder Woman from her romantic meeting with Superman, and the Man of Steel follows the Amazon Princess to Olympus, but they arrive in different locations. After Hermes explains to Diana that Olympus has been taken over by Darkseid, the New God toys with the heroes, making them battle, as he discusses with Desaad his plans to use Olympus as his base to conquer the universe. When Superman and Wonder Woman find Darkseid and point out that he has conquered nothing and that the Olympians have abandoned their home, Darkseid sets off explosives he had set throughout Olympus and leaves. But Olympus immediately regenerates and Wonder Woman and Superman return home as friends. |

| Notes | Recounting the 1st meeting of the post-Crisis redone versions of each character. Story continues from ADVENTURES OF SUPERMAN (DC, 1987 series) #440 and from WONDER WOMAN (DC, 1987 series) #16. Story broken up into chapters: "Chapter One: First Date...," pp. 1-7; "Chapter Two: Fallen Idols," pp. 8-12; "Chapter Three: Broken Mirrors," pp. 13-20; "Chapter Four: Battle!," pp. 21-24; and "Chapter Five: This Hollow Victory...," pp. 25-32. Darkseid tells Desaad that the Olympian gods are creations of the same energy released by the battle of the old gods that created Apokalips and New Genesis, though Circe describes a very different process of generation of the gods in Wonder Woman #19 when she explains to Diana that the New Gods had their genesis in the energy released by the Titans conflict with the Olympians. |
